Application filed September 20, 1916. Serial N 0. 121,230.

To all whom it may concern:

Be it known that I, PETER SCHMID', a citizen of the Swiss Republic, and resident of Basel, Switzerland, have invented a new and useful Apparatus for the-Weighting of Silk Flaments and Silk Fabrics in F orm of Hanks. I

The present invention relates to an ap paratus for the weighting of silk in hanks by means of which it is possible to carry out all the operations of weighting of silk, excepting the treatment with baths of metal chlorid, namely 1- v 1. The tin Washing, that is to say, the washing away of the superfluous tin salt by rinsing with water.

2. The phosphating, that is, the treatment of the silk 1n a bath of sodium phosphate.

3. The washing out with soft water. 4. The following treatment with dilute acid.

5. The treatment in a bath of water glass instead of the treatment with acid, after the last bath of'sodium phosphate.

6. A further washing, and

7. The soaping.

The apparatus hasthe'advantage that it enables all these four or seven operations to be carried outso that the silk does not need to be touched between the said operations, thus securing a great advantagein the saving of time. labor and material, and the silk suffers at the same time considerably less.

In this newapparatus there is provlded a vat furnished atthe top with a row of horizontal hank supports and at the bottom with a heating apparatus. The vat has on the one hand above the hank supports spraying tubes which can all be turned back, and on the other hand it has spraying tubes arranged below the said hank supports, of

wvhich each separate tube is connected with the corresponding hank support and can be turned back with it, so that an intensive spraying of the silk hanks can be effected with the respective liquids employed, and this equally effectively when the said liquids are kept in-circulation by means of a pump or are supplied through special delivery pipes under pressure to the respective spraying tubes.

' In the accompanying drawing is illustrated a construction of the invention in which Figure 1 shows the apparatus in. longitudinal sectional elevation and Fig. 2

resistant to alkali and acid, with or without interior lining of enamel. At'the bottom Patented June 26, 1911?.

of the vat is placed a heating coil (1 ofa metal resistant to alkali and to acid. This heating coil serves to convert the liquids used, as for instance, the lye of sodium'phosph ate or the bath of water glass, when de-' sired, into foam; and it also serves as a preliminary heater of the washing water. The depth of the vat is from 1.20 to 1.50 meters more or less, according to the quantity of the silk to be treated. In the upper third of the vat are placed the hank supports B on which the silk hanks are suspended. The supports are constructed of material resistant to alkali and to acid and may suitably be of glass or porcelain. Parallel to each placed vertically underneath a spraying tube 6. and above the hank supports are placed similar irrigation tubes 0.- The upper spraying tubes 0 are connected together and have a common inlet from a rotatable supply tube C with balancing counter-weight (Z; they can all be raised simultaneously by moving the tube C so as to leave the hank supports B free. The lower spraying tubes I) have likewise a common supply through a main tube D, but they can each separately be turnedaround the axis of the main tube D and be lifted up together with the hank support B above each of them, each separate tube 6 being connected by means of a guide rod E with the corresponding hank support. Each hank support is capable of being turned upward in the well known manner as already set forth in Swiss Patent N 0. 60,685, in order that the silk hanks can be easily suspended upon or removed from them.

Above the vat there is placed a reservoir F for the reception of the solution of sodium In the vicinity of the vat is placed a pump G for the delivery of this lye out of the vat through the tubes 79, 9, into the reservoir F placed above also serves to cause the Washing water or the Washing liquid or other fluids for treatment afterthe phosphate bath or after the water glass bath, when necessary, to cirou late through the tubes 7) and 1", into the tubes C and D and over the silk. Close to the vat hank support is there is placed, as set forth in SwissPatent No. 60685, a mechanism If for turn ng the supports during the treatment of the silk.

follows 2- The apparatus is operated as through the The tubes O, Dare connected pipe m,- 11. provided with suitable stopcocks I alternately washing machine and thoroughly rinsed out;

with supplies of hard and soft water respectively'or by means of the tubes 0 with the reservoir F. The silk which has been removed from the tin salt bath and wrung out is placed upon the hank supports so that on each separate hank support B is placed from one to two kilos of silk. The spraying device is set in operation and theha-nk supports are turned. The silk isthereby moved to and fro as in an ordinary After about three minutes the spraying device is stopped and the water which has washed out the tin salt is allowed to run away through the pipe s of the vat. The upper row of tubes 0 is lifted up. From the upper reservoir F the sodium phosphatelye is admitted through the tube 0 into the means of the heating coil 0, the phosphate lye is heated and caused to foam. The foam rises, envelops the silk entirely, and is maintained thus for from one empty vat A; by

- half to two and a half minutes.v During this tubes 0, D to the extent liters of soft Water for each kilo of silk, and

:time the hank supports are moved-slowly.

The steam is then shut off, the foamfalls down, and the liquid is pumped back by means of the pump G into the upper reservoir F. In order to recover the sodium phosphate which still adheres to the silk the same is rinsed with about 10 liters of soft water for each kilo of silk in a circulat ing manner, and these rinsings which have,

removed the sodium phosphate from the silk are also pumped back into the reservoir F. By this addition the sodium phosphate liquid is not diluted because during the foaming a certain quantity of water has been evaporated which is replaced by this washing liquid.

From the soft water supply is then admitted into the vat through the spraying of from 50 to 70 the circulating liquid is passed over the silk by means of the spraying pipes for a period of about 10 minutes. This water is then dis- After this the charged through the pipe 8. same quantity of fresh soft water is delivered into the vat through the spraying device, a little quantity of acid is added and l the circulating liquid is again delivered over minutes. The silk is the silk for about five then removed from the hank supports B and is subjected to the usual further operations, that is to say, the silk is ready for the next treatment with chlorid of tin.

After the final bath of phosphate it is only 'washed with water and then in the vat itself the water glass bath is prepared and, when desired, the water glass is brought into contact with the silk in the form of foam. After this the water glass is discharged through the pipe s. When desired, the silk is treated with acid and soaped by circulating liquid. v

It is obvious that all or only a part of the above described operations may be'carried out by means of the apparatus.
